Monroe has served as Lambert's BFF for nearly a decade, but she's also grown quite close to Shelton over the years. The 28-year-old singer was recently featured on Shelton's hit single "Lonely Tonight," and The Voice coach even served as the officiant at her 2013 wedding to White Sox pitcher John Danks. (Lambert, of course, served as the maid of honor.)
"I just look up to her so much," Monroe told ET of Lambert at the ACM Awards this year. "I've known her for 10 years and we've been best friends for almost 10 years, but I still watch her shows every night when I'm on tour with her and anytime I'm out on the road just hangin' out, I just watch her because she just blows me away. She's the real deal, for sure."
Lambert echoed similar sentiments about her friend in an interview with ET, saying: "She's a great country singer and she's inspiring to me."
But can we please go back to this bizarre baby stroller footage?! A rep for the "Sangria" singer tells ET: "He knew the paparazzi was there and was just being funny." What do you think of the stunt? See it all go down in the video below.
